本発明は染着性向上剤、更に詳しくは分散型カチオン染
料のアクリル繊維又はカチオン可染ポリエステル繊維に
対する染着性を向上させる薬剤に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a dyeability improver, and more particularly to an agent that improves the dyeability of dispersed cationic dyes to acrylic fibers or cationically dyeable polyester fibers.
分散型カチオン染料例えばカヤクリルＥＤ染料は周知の
とおりアクリル繊維の混紡、混繊品等に対する一浴染色
用として最適の染料であり、各種属の染料（酸性染料、
分散染料、直接染料等）との相溶性が極めてずぐれたも
のである。また中性浴付近での染色が可能なため相手染
料の選択の幅が極めて広く染色条件の設定が容易であり
、更には再現性が良いため安心して染色できることから
広く使用されている。Dispersed cationic dyes, such as Kayacryl ED dyes, are well-known dyes that are most suitable for one-bath dyeing of acrylic fiber blends and mixed fiber products.
It has extremely poor compatibility with disperse dyes, direct dyes, etc.). In addition, it is widely used because dyeing can be carried out in a neutral bath, which allows for a wide range of selection of partner dyes, making it easy to set dyeing conditions, and because it has good reproducibility, it can be dyed with confidence.
しかしながらこれらの染料中には濃色を使用すると吸尽
率が低く染色に時間がかかるものがあり、省エネルギー
上好ましくなく、前記の長所を助長すると共にこの様な
欠点を改良して染着性を向上せしめることが要求され、
この点でなお改良すべき余地が残されていた。However, some of these dyes have a low exhaustion rate and take a long time to dye when dark colors are used, which is undesirable in terms of energy conservation. It is required to improve,
There was still room for improvement in this respect.
本発明者らはこのような現状に鑑み鋭意研究の結果本発
明を完成し上記問題点を解決した。In view of the current situation, the present inventors completed the present invention as a result of intensive research and solved the above problems.
すなわち本発明は、安息香酸とプロピレングリコールと
のエステルを使用することを特徴とする分散型カチオン
染料のアクリル繊維又はカチオン可染ポリエステル繊維
に対する染着性向上剤である。That is, the present invention is a dyeability improver for acrylic fibers or cationically dyeable polyester fibers using a dispersed cationic dye, which is characterized by using an ester of benzoic acid and propylene glycol.
本発明の安息香酸とプロピレングリコールとのエステル
を助剤として染色時に使用すると 最終）
吸尽率は１０〜２０％向上せしめることが可能となり、
かつ残浴改良もできる。しかも色相は更に鮮明になり、
染色の堅牢度も、充分に維持することができる。When the ester of benzoic acid and propylene glycol of the present invention is used as an auxiliary agent during dyeing, the exhaustion rate can be improved by 10 to 20%,
Also, it is possible to improve the residual bath. Moreover, the hue becomes even more vivid,
The fastness of the dyeing can also be maintained satisfactorily.
本発明の染着性向上剤、すなわち安息香酸とプロピレン
グリコールとのエステルは、例えハ安息香酸ブチル（ま
たはメチル、エチル、プロピル等）リン酸又は硫酸を触
媒としてプロピレングリコールによりエステル化するこ
とによって得られる。The dyeability improver of the present invention, that is, the ester of benzoic acid and propylene glycol, can be obtained by esterifying butyl benzoate (or methyl, ethyl, propyl, etc.) with propylene glycol using phosphoric acid or sulfuric acid as a catalyst. It will be done.
具体的に一例をあげれば
安息香酸ブチル １モル １７８ｇプロピレングリ
コ−Ａ／１モル ７６．９リン酸
１０ｃｃ上記を混合し窒素ガス気流中で
１４０〜１５０℃まで昇温する。To give a specific example, butyl benzoate 1 mole 178 g Propylene Glyco-A/1 mole 76.9 phosphoric acid
10 cc of the above was mixed and heated to 140-150°C in a nitrogen gas stream.
昇温につれ１３０℃附近よりブタノールが分Ｓしてくる
。同温度で約５時間維持し６０ｃｃ分離した時点で冷却
し反応を止めてエステル化物を得る。As the temperature rises, butanol starts to decrease from around 130°C. The temperature was maintained for about 5 hours, and when 60 cc was separated, the mixture was cooled to stop the reaction and obtain an esterified product.
なお、Ｉ／ン酸触媒はまたＨ、 Ｓ Ｏ４によっても生
成することができ、使用量は最モルである。Note that the I/phosphoric acid catalyst can also be produced using H, SO4, and the amount used is the maximum molar amount.
このエステルにノニルフェノール非イオン１０モルを添
加して使用に供すると、良好な分散性ないしは可溶化状
態が得られ本発明の効果が一層発揮される。When 10 moles of non-ionic nonylphenol are added to this ester before use, a good dispersibility or solubilization state is obtained and the effects of the present invention are further exhibited.

向上せしめ、かつその染着堅牢度を維持せしめうるもの
である。本発明の染色性向上剤は染色時染料と共に使用
すればよく低温より染着が始まり染着性は極めて良好と
なる。The fibers to be dyed include acrylic fibers, cationic dyeable polyester fibers, and Lumilette (a polyester product name manufactured by Toshisha Co., Ltd.), and the dyes used are dispersed cationic dyes, such as Kayacryl ED dyes, which have significantly improved dyeability. The color fastness of the dye can be maintained. The dyeability improver of the present invention may be used together with a dye during dyeing, and dyeing starts at low temperatures and the dyeability is extremely good.
